After 1 year, $800 deposited in a savings account with simple interest had earned $64 in
interest. What was the interest rate?
Use the formula i = prt, where i is the interest earned, p is the principal (starting amount),
is the interest rate expressed as a decimal, and t is the time in years.

8%

Step-by-step explanation:

We will use the equation provided to solve this problem.

Lets plug in the values:

    First, divide both sides by 800.

        Multiply x by 1

Now, we multiply .08 by 100 to get our interest rate:

(.08)100 = 8

The interest rate is 8%

the answer is simply just 6n add the two together as they have an n

the answer would be c:   ax + b = ax + c
